Question about 2004 Derbi Senda SM 125 4T
Sounds like your chain is stretched and not fitting the sprocket properly or is just too loose. Check your front and rear chain sprockets for wear and ensure the teeth are straight. Check to insure the chain fits snuggly on the rear sprocket. As a chain stretches over its life, it won't fit in all of the teeth on the rear sprocket. This will cause the chain to ride up on the teeth at higher RPMs and jump (causing the feeling of a jolt or **** as it grabs again). Typically, the chain should have no more than an inch or so of play when properly adjusted.
